We provide a complete line of wear-resistant castings for all shredder applications including special design requests.  Depending on the feedstock, location, application, and other important considerations, we provide several special grades of manganese steel for maximum results and a lower cost per shredded ton.  Certain items like hammers and rotor caps can also be provided in our CS family of martensitic low alloy steels containing chromium, nickel, and molybdenum. We constantly redesign shredder components to accommodate the specific needs of individual customers for any application.

The common wear parts for metal shredders include:

• Shredder hammer
• Rotor and caps
• Shredder grates
• Double bean grates
• Wall conversions
• Infeed and side liners
• Breaker bars and anvils
• Roof covers
• Kickout and reject doors

Shredder Hammers

Shredder hammers are the main shredder wear parts, which install in the rotor and direct to crush raw material. The shredder hammers are manufactured by manganese steel, alloy steel, and our patent TIC inserts steel.

Hammer Pin Protectors

The standard material for these hammer pin protectors is also manganese steel.

Pin protectors protect the long pins that secure the hammers in place. Depending on the shredder size, pin protectors can weigh hundreds of pounds and are typically replaced after 5-10 hammer changes, or about every 1-2 weeks of operation.

Reject Door

Reject doors in the back upper housing are furnished for ejecting unshreddable items. These reject doors are manufactured by manganese steel or alloy steel.

Available with specialty hole sizes, ribs, and counterweight styles, plus reversible designs for increased wear life.

Shredder Grates

The shredder grates ensure that shredded metal does not leave the shredding zone (hammermill) until shredded metal pieces are reduced to the desired size. The characteristics of the shredder grate’s openings are determined by shredded-metal specifications and operating parameters. The shredder grates sustain substantial abrasion and impacts from the rapidly moving metal inside the hammermill.

 

Breaker Bars & Anvils

Breaker bars provide internal reinforcement against the impact force of hammers on the metal being shredded. Anvils provide an internal surface where feedstock material is introduced into the hammermill and initially impacted by the hammers. Breaker bars are often replaced at the same time as anvils and grates.

Qiming Casting’s high strength alloy and manganese anvils are designed to be direct OEM replacements. Upper and lower units are customs engineered to provide increased performance to specific shredding applications.

Shredder Caps

Rotor and end disc caps protect the rotor from damage by the metal being shredded in the hammermill. Depending on shredder size, caps can weigh hundreds of pounds. Caps are replaced after about 10-15
hammer replacements, or about every 2-3 weeks of operations.

Infeed and side liners

Liners internally protect the shredder from damage by the metal being shredded in the hammermill. Liners sustain substantial abrasion and impacts from the rapidly moving metal inside the hammermill. Depending on shredder size and material being shredded, liners may need replacing after 100,000-200,000 tons of material have passed through the shredder.
